UNASSIGNED
In this study, we aimed to evaluate vitamin D and vitamin D receptor levels in children with attention-deficit/hyperactivity disorder (ADHD).
UNASSIGNED
In this cross-sectional study, a total of 80 children including 40 ADHD patients (aged 6-12 years; 28 males and 12 females) and 40 age-,
BACKGROUND
The phosphatase PTEN represents an important physiological inhibitor of phosphatidylinositol-3 kinase (PI3-K)/protein kinase B (Akt) signalling, however, the functional role of PTEN in the initial phase of angioplasty-induced vascular injury remains elusive. In the present study we sought
The plant hormone abscisic acid (ABA) controls growth and development and regulates plant water status through an established signaling pathway. In the presence of ABA, pyrabactin resistance/regulatory component of ABA receptor proteins inhibit type 2C protein phosphatases (PP2Cs). This, in turn,
Placental alkaline phosphatase (PLAP) was measured by an immunoradiometric assay using the monoclonal antibody C2 (PLAP-C2). Serum samples of 135 patients with epithelial ovarian cancer were analyzed, and the results were compared with CA125 levels. CA125 and PLAP-C2 were elevated in 85 and 43% of
Alkaline phosphatase (ALP, EC 3.1.3.1) is a membrane-bound metalloenzyme that consists of a group of true isoenzymes, all glycoproteins, encoded for by at least four different gene loci: tissue-nonspecific, intestinal, placental, and germ-cell ALP. Through posttranslational modifications of the
The hypoestrogenic state induced by gonadotropin-releasing hormone agonists (GnRHa) has been shown to be effective in the treatment of uterine leiomyomas but to induce bone loss. Estriol has been described to be a weak and short-acting estrogen without an increased risk of endometrial proliferation
BACKGROUND
Attention-deficit/hyperactivity disorder (ADHD) is the most frequently diagnosed neuropsychiatric disorder of childhood. The etiopathogenesis of ADHD has not been fully defined. Recent evidence has suggested a pathophysiological role of vitamin D deficiency in ADHD. In this study, we
BACKGROUND
Attention-deficit-hyperactivity disorder (ADHD), one of the most common psychiatric disorders of childhood, has an early onset, affecting 2-18% of children worldwide. The etiopathogenesis of ADHD is obscure. In recent studies, a low level of vitamin D has been found in association with
Alkaline phosphatase (ALP) is a vital hydrolysis enzyme in phosphate metabolism, which catalyzes the hydrolysis of phosphate ester groups in proteins, nucleic acids, and other small molecules. Meanwhile, abnormal ALP expression is associated with occurrence and development of many diseases. Terminal
There is mounting evidence implicating cytokines such as interleukin-1 in the local regulation of bone homeostasis. In this report we show that recombinant human interleukin-1 beta (rhIL-1 beta) influences several activities of osteoblast-like cells derived from human trabecular bone explants in
Tyrosine hydroxylase, which plays a critical role in regulation of dopamine synthesis, is known to be controlled by phosphorylation at several critical sites. One of these sites, Ser40, is phosphorylated by a number of protein kinases, including protein kinase A. The major protein phosphatase that
The single-copy mouse gene Ptprr gives rise to different protein tyrosine phosphatase (PTP) isoforms in neuronal cells through the use of distinct promoters, alternative splicing, and multiple translation initiation sites. Here, we examined the array of post-translational modifications imposed on
Protein tyrosine phosphatases have been implicated in the regulation of serotonergic and dopaminergic activity in the central nervous system. In a recent study we found that nonA/nonA homozygosity at the locus codifying for the low molecular weight protein tyrosine phosphatase (ACP1) was associated
Src family protein tyrosine kinases (PTKs) play an essential role in antigen receptor-initiated lymphocyte activation. Their activity is largely regulated by a negative regulatory tyrosine which is a substrate for the activating action of the CD45 phosphotyrosine phosphatase (PTPase) or, conversely,
Proteinase-activated receptor-2 (PAR2), a new member of family of the G protein-coupled receptors, is activated by proteolytic cleavage of its extracellular amino terminus, a mechanism similar to that used by the thrombin receptor. It has been suggested that PAR2 has a potential role in the late
